Opened: Feb 09, 2018

Severity: 3-Major

Symptoms

TMM might leak memory when performing DNSSEC signed zone transfers. You can detect this issue by examining system memory before and after performing zone transfers. For example: tmsh show sys memory raw | grep dnssec

Impact

TMM leaks memory related to the signed zone transfer.

Conditions

-- Dynamic DNSSEC signing of zone transfers is configured for a given zone from an authoritative DNS Server (this could be on-box BIND, off-box BIND, etc) or from DNS Express.

Workaround

There is no workaround at this time.

Fix Information

TMM no longer leaks DNSSEC zone transfer related memory.
